Long before CHC....ACN was an excellent operator. The CHC debacle rests on CHC as they jumped into something thinking they were the Bee's Knees but in reality knew nothing of what they were doing in Nigeria.
It is not a question of standards but rather of business sense.
You don't take a bunch of folks from Canada...plunk them down in Nigeria....ignore the local staff's abilities and experience and make a great success of things.
They lost tons of money....but that is the price you pay when you thumb your nose at the "system".
Bristow finally saw the light and began including Nigerians in their senior management system and one can see the business growing as a result.
CHC went the othere direction and we see how that worked!
